    If you want to update it’s not required to remove the package before. You can directly execute update command:

    yum update cmake

    the cmake you use was installed manually, not using yum.

    yum info shows you the information of the package that is available in your repositories (base), it is not installed, otherwise it would say

    Repo : installed

    so since cmake is not installed using yum, you cannot remove it using yum.

    NOTE: you can also see that the version numbers differ…
